The signature of org.apache.log4j.helpers.Loader.getResource() has changed
between 1.1 and 1.2. In 1.1, it is:
public static URL getResource(String resource, Class clazz)
In 1.2, it changed to:
public static URL getResource(String resource)
We are using 3rd party software that relies on the first method signature, so we
see a NoSuchMethodError when using 1.2. We would like to updated to 1.2 to
make use of the MDC class. Can a backwards compatibility method be added to
this class?

Compatibility method added to both v1_2-branch and HEAD. Excellent timing since a 1.2 maintenance
release (1.2.12) is imminent. Please report any other issues as quickly as possible since no additional
work on the v1_2-branch is currently planned after the release.
To check out the v1_2-branch source
cvs -d:pserver:anoncvs@cvs.apache.org:/home/cvspublic co -r v1_2-branch logging-log4j
The HEAD as many known compatibility issues with 1.2 which we are working to resolve, so it is highly
unlikely that it could act as a drop-in for log4j 1.1 at this time.
